Specification of Letters Patent.

Patented Nov. 26,1912.

Application filed April 1e, 1912. Serial 110. 091,109.

To all whom it may concern.

Be it known that I, JOHN H. sA uns, a citizen of the United States,residing at Galion, in the county of Crawford and State of Ohio, haveinvented certain new and useful Improvements in'Mufllers, of which thefollowing is a specification.

This invention relates to new and useful improvements in mufllers and isparticularly designed to provide a' device of this character which maybe attached to the exhaust pipe of the engine in such a manner that theproducts of combustion may be emitted without the usual accompanyingnoise of the explosions.

In carrying out the present invention it 18 one of the objects toeliminate compression within the mufller casing, which, underordinaryvcircumstances, reduces the power obtained from the engine, dueto the back pressure.

With the above and other objects in view, my invention consists in theconstruction, combination, and arrangement of parts, all as willhereinafter be more fully described, illustrated and claimed, whereinFigure 1 is a central longitudinal section of the mufiier constructed inaccordance with the present invention. Fig. 2 is a vertical sectiontaken along line 2-2 of Fig. 1. Fig.

3 is a similar View taken along line 3-3 of Fig. 1. Fig. 4 is likewise avertical section takenalong line 4-4 of Fig. 1.

' The mufiler forming the subject matter of the present inventioncomprises a tubular funicular casing having a head mounted in oneterminal thereof, said head being pierced by an inlet pipe, which isthreaded into said head and is perforated upon the inner terminalthereof, the outer terminal of said pipe being adapted to engage theexhaust pipe of the engine. A funicular discharge opening is secured inthe outer terminal of said casing by fneans of a plurality of rods,threaded into said funicular member, and piercing the head aforesaid. Aplurality of batlle plates are mounted upon these rods and are piercedby openings which are staggeredly arranged for the purpose of divert-'ing the passage of the gases from a direct course. In carrying out thepresent invention a muffler casing 10 constitutes the main body portionthereof, and is interposed between the inner terminal of the exhaustpipe of the engine and the exterior atmosphere. A head 11 is mountedupon the interior of the inner. terminal of the casing 10, said headbeing encircled by a flange 12, which is adapted to rest against theinner terminal of said casing, when the top of the head 11 is placed inits operative position. Y An inlet pipe 13 is concentrically threadedinto the head 11, and has its inner terminal closed by the cap 145. Theouter terminal of this pipe 13 is connected by a union 149- to theexhaust pipe 15 of the engine. The body of the inlet plpe 13 adjacent tothe inner face of the head 11 is provided with a plurality ofperforations 16, while the terminal thereof'adjacent to the cap 14; ispierced by the alined perforations 17, said perforations 16 and 17providing a means whereby the gases or products of combustion passingfrom the exhaust pipe 15 into the supply pipe 13 may escape into thecasing 10. A funicular discharge pipe or tube mounted at the oppositeend of the casing 10. The inner terminal of this funicular dischargepipe or tube is provided with straightened portion 19, which is reducedto be received within the terminal of the casing forming a flange orbead 20 which bears against the terminal of said casing. The innerterminal of this funicular discharge tube or pipe has a plurality ofrods 21 threaded therein, which extend through the casing 10 adjacent tothe walls thereof and project through the head 11. The outer terminalsof these rods 21 are threaded to receive the nuts 22 which bear againstthe outer surface of the head 11 and clamp the same in its operativeposition.

A plurality of battle plates illustrated three in number 23, 23 and 23,are mounted upon the rods 21 adjacent to the funicular discharge pipe ormember 18. The

bafile plate 23 is provided with a circular opening 23" therein, locatedadjacent to the circumference thereof, while the baflie plate 23 isprovided with a similar opening 23, and the baflle plate 23 is providedwith an opening 23, said openings in the battle plates being arranged asillustrated in Fig.

4, in such a manner that the same are in no plates 23, 23 and 23, in acourse such as heretofore described, and thence out of the funiculardischarge tube or member 18. It will clearly be seen that theconstruction of the funicular discharge opening provides a means for theexhaustion of the gases,

which is of greater diameter than the inlet, and thus prevents thecreation of pressure or the accumulation of gas within the casing, andthereby eliminates the back prewire which has been so common in mufilersnow in use. This construction readily eliminates any decrease in theower from the engine and increases the utility, speed, and operationthereof.

Havin thus fully described my invention, what I cIaim is new and desireto secure by U. S. Letters Patent, is

1. In a mufiier, the combination with a casing, of a head provided withan aperture, a flange formed with the head and engaging the casing, aninlet pipe provided with a plurality of dperforations adjacent to thehead mounte in the head and projectin into the casing, a cap on theinner termina of the inletpipe adjacent to other rforations in the inletpipe, a funicular discharge member on the end of the casing opposite tothe head, a plurality of rods connecting said head and said dischargemember, and a pigrality of battle plates mounted upon the r s.

-2. In a mufiler, the combination with a casing, of a funiculardischarge member at one terminal thereof, a head located in the inletterminal thereof, and three bafile plates transversely of the casing andadja-' cent to the funicular discharge, each plate provided with'asingle aperture larger than the inlet adjacentto its periphery, theseveral apertures spaced one hundred and twenty degrees radially fromthe aperture in the-adjacent plate.

In testimony whereof I afiix my signature in presence-0f two witnesses.JOHN H. SAMES. Witnesses:
